Bently Nevada 3500/15 125840-02
Low Voltage AC Power Input Module
🧾 Product Overview
The 3500/15 125840-02 is a low-voltage AC Power Input Module (PIM) designed for use within the 3500 Series machinery protection system. It accepts AC input power in the range of 85–132 VAC, converts it into regulated DC power, and delivers it to the entire rack system to power all installed modules.
The 3500/15 is designed to fit into the left-most slot of the 3500 rack and occupies a half-height form factor. The 125840-02 version is configured for low-voltage AC input, as opposed to high-voltage AC or DC variants. This module supports hot-swapping and can function either as a primary or backup power source, making it ideal for systems requiring redundancy and zero downtime.
